Google+ Search

See the search box? Looks familiar, right? It should, it's Google.com search, finally baked into Google+. Before, you could only search for other Google+ users. Now you can search Google+ posts, news and the Web. Google said it returns results based on content in which users show interest.

Google+ launched from limited field testing to full beta Sept. 20, which means any user (except Google Apps suite users) can join the service as Google seeks to extend its social network to Facebook's 750 million-plus users. The beta launch was accompanied by a number of new features. These include a search feature and several improvements to the popular Google+ Hangouts group video conferencing application, which lets up to 10 users at a time to hold court in a session via their computers. Actually, Google is now letting its Android handset users access Google+, too, thanks to a new mobile application. Take this quick tour of the new Google+ features, which are also being touted on the Google.com home page.
